lMPROVEI/VIENT IN STUCCO ORNAMENTS. i

{Specification forming part of Letters Patent No. 139,781, dated June10, 1873 application filed IApril 2, 1873.

To all whom t may concern:

Be it known that I, A. DESIRE GODARD, of

` Chicago, in the county of Cook andState of Illinois, have invented anew anduseful Improvement in Fire-Proof Stucco Ornaments,

fof which the following is a speciication:

The'object of my invention is to produce nre-proof stucco ornaments foi`use as centery pieces, angle-pieces, for ceilings, cornices, andbrackets, flower-drops, scrolls, leaves, and a ness.

ylo this end my improvement consists in` `making such ornaments of thinlayers of a compound composed principally of plaster'of Paris and glue,and interposing between the y layers of the plaster a webbing of burlap,or

jute, ora similar textile fabric having open meshesl readily penetratedby the plasticmaterial.

Io the compound of plaster of Paris and glue may be added phosphate ofsoda and ,borax, to increase its hardness and reproof quality, also alumto prevent the warping of the ornament while setting; also more or lessrock-salt, according asy it may be desirable to cause the setting of thecompound more or less rapidly.

The mortar may be prepared by dissolving onepart of glue in one hundredparts of water, moderately Warm, to `which should be added plaster ofParis sufcient to make aliquid paste of )the consistency of oil-paintwhen i ready'for use; however, I Apreferably add to these ingredientsone part of phosphate oi soda, one part of borax, one part of alum, andThe proportion oi rock-salt should be less when a slower setting ot' themortar is required; maguesia or even mother-Water may be substituted forrocksalt, Whenever the former may be procured t0 advantage. y {In`making ornaments I first cover the mold or matrix, by means of a stiffbrush,

Witnesses:

with a thin layer of theabove-mentioned mortar, then place upon suchlayer a webbing of burlap, jute, or the like fabric, and then againspread a layer of the mortar upon the burlap until it is entirelyembedded. The artist by using the brush can Vreach into all cavities andbeneath all undercuts, and thus reproduce Without diiculty the true formof the mold.a The textile webbing used should be of the re-proof kind,such as is employed in theaters for screens for the foot-lights.

Ornaments thus made will be exceedingly light and strong, and, beingmade tough by the introduction of a` textile webbing, are

proof against breaking or cracking, unlike those made of plaster ot'Paris alone.

The smaller ornaments, such as cornices of ordinary size, require noother `fastenin g than that aiorded by rows of nails driven through themalon g their edges into their supports. Ad-

ditional fastening andfsupportin g devices may, however, be used withthese as well as with those ot' larger size.

In the accompanying drawing, which illus-` trates a cornice in section,Arepresents the compound of plaster of Paris and glue, 85e.,

and B the textile webbin`g,'ot' which two thicknesses are shown asemployed.

What I claim, as my invention and desire to secure by Letters Patent, is

1. Fire-proof stucco ornaments, composed of a compound of plaster ofParis and glue in layers, and an interposed textile webbing,substantially as speciiied.

2. Fire-proof stucco ornaments, composed of a textile webbing embeddedin layers of a compound prepared by mixing in Water plaster of Paris,glue, phosphate of soda, boraxy` alum, 'and rock-salt, substantially andas A for the purpose speciiied.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
